Constructor Detail

ParallelWays

public ParallelWays(java.util.Collection<Way> sourceWays,
                    boolean copyTags,
                    int refWayIndex)

Constructs a new ParallelWays.

Parameters:

sourceWays - source ways

copyTags - whether tags should be copied

refWayIndex - Need a reference way to determine the direction of the offset when we manage multiple ways

Method Detail

copyNodeInMap

private static void copyNodeInMap(java.util.Map<Node,Node> splitNodeMap,
                                  Node node,
                                  boolean copyTags)

isClosedPath

public boolean isClosedPath()

Determines if the nodes graph form a closed path

Returns:

true if the nodes graph form a closed path

changeOffset

public void changeOffset(double d)

Offsets the way(s) d units. Positive d means to the left (relative to the reference way)

Parameters:

d - offset

commit

public void commit()

Performs the action by adding a new sequence command to the undo/redo queue.

makeAddWayAndNodesCommandList

private java.util.List<Command> makeAddWayAndNodesCommandList()

copyNode

private static Node copyNode(Node source,
                             boolean copyTags)

getWays

public final java.util.List<Way> getWays()

Returns the resulting parallel ways.

Returns:

the resulting parallel ways
